Renewed September 10, 1937 24 Claims This invention relates tothe manufacture of 7 shoes and is illustrated as embodied in a machine for splitting sole blanks.

In the manufacture of shoes it is common practice to split a sole blank which has been shaped to the proper outline, to form a skeleton insole having an opening in its forepart and to form an outsole the forepart of which has a central projection which is substantially complemental to the opening of the insole. In the finished shoethe central projection of the outsole engages within the recess of the insole, the overlasted margin of the shoe upper being included between the respective margins of the insole and the outsole in accordance with the usual practice.

It is desirable that the forepart of the skeleton insole and the central projection of the outsole shall form a substantially continuous surface which provides a comfortable foundation for the foot. Accordingly, when the sole is split by the use of a knife, it is common to remove suflicient material from the upper face of the margin of the split outsole to compensate for the thickness of the overlasted margin of the shoe upper, thereby insuring that the central projection of the outsole and the forepart ofthe insole shall form a substantially continuous foot-supporting foundation such as referred to'above.

In order that it will be unnecessary after splitting the sole blank to remove material from the margin of the .forepart of the split outsole as above described, and accordance with a featureof this invention, there is providedsplitting i and reducing means such,for example as a saw,

means for effecting relative displacement of the central portion of the forepart of a sole blank ontheone hand and the marginal portion of the forepart of the sole blank on the other hand, and mechanism for feeding the distorted sole blank past the splitting and reducing means to split from the sole blank a skeleton insole and outsole, the combined thicknesses of the marginal portions of said insole and outsole being less than the thickness of the sole blank.

In the illustrated machine the saw is of the band type and travels over a hollow pulley which guides the trimming section of the saw for movement in. a'circular path. The sole blank is supported upon the peripheral face of a matrix drum which is operatively connected to a rotatable feed member for moving the sole past the cutting section of the saw. The sole is progressively distorted in'accordance with the shape of the peripheral face of the drum by a plurality of presser fingers which force the sole against said face, the central portionof the forepart of the sole blank being forced below the trimming section of the saw to form the opening in the forepart of theskeleton insole and to form the central projecting portion of the split outsole. The matrix drum and the feed member are continuously rotated, the feed member and the presser fingers being moved away from the drum during a predeterminedarc of travel of the drum in order to permit sole blanks to be inserted in the machine. Gages are also provided for positioning the sole lengthwiseand widthwise with relation to the matrix drum when the feed member I and the presser member are swung away from the drum.

These and other features ofthe invention, including certain details of construction and combinations of parts will bedesoribed as embodied in anlillustrated machine and pointed out in the appended claims.

Fig. 10 is a perspective view showing a skeleton insole and outsole which have been split from the sole blank by the use of the above machine; and

Fig. 11 is a transverse section of the forepart of a shoe in which the insole and outsole have been incorporated. i

The machine is illustrated-with reference to splitting an outsole 20 (Fig. 10) and a skeleton insole 22 from a sole blank 24 (Figs. 2 and 3). The sole blank 24 is progressively forced against insure that an effective rolling fit the periphery 26 of a matrix drum 28 by a presser member 30 (Fig. 3) as it is moved past a cutting section 32 of the band saw 34 by a feed member 36, the forepart of the sole blank 24 being distorted transversely as it is moved past the cutting section 32 in order to form in the forepart of the insole 22 an opening 38 which is substantially complemental to a central projection 40 of the forepart of the outsole 20.

When the outsole 20 and the insole 22 have been incorporated in a shoe 2I (Fig. 11) the central projecting portion 40 of the outsole and the margin or rand 23 of the insole have their upper surfaces flush with each other to form a substantially continuous face which serves as a comfortable support for the foot. It will be noted that the overlasted margin 25 of the shoe upper is positioned between the rand 23 of the insole 22 and the margin of the forepart of the outsole 20 and that if the projection 40 of the outsole is to be flushw-ith the rand 23 of the insole the thickness of the overlasted counter portion 25 of the shoe should be compensated for by forming an outsole 20 the thickness of the projecting portion 40 f which is substantially equal to the combined thickness ofthe margin of the forepart of the outsole 20, the overlasted portion 25 of the shoe upper, and the rand 23 of the insole. As above stated, after splitting a skeleton insole and an outsole from a sole blank by the use of a knife, it has been proposed to remove material from the upper face of the margin of the forepart of the outsole in order to compensate for the thickness of the overlasted margin of the shoe upper. In the illustrated machine the kerf removed by the saw is of substantially the same thickness as the overlasted margin of the upper and it is therefore unnecessary to reduce the margin of the forepart of the outsole as above described.

The band saw 34 is mounted upon a lower pulley (not shown) and upon an upper pulley 42 which is rotatable upon roller bearings 44, 46 and 48 (Figs. 1 and 3.) The-pulley 42 has a circular groove 50 of suitable shape to receive the bearings 44, 46 and 48 and has a tapered portion 52 beyond which the cutting section 32 of the saw 34 projects. The tapered portion 52 of the pulley 42 forms a flaring opening 54 which is shaped to receive the matrix drum 28 and in.- cludes the forward'end of a tray 56 arranged to receive the split outsole. The skeleton insoles 22 are grasped by the operator as they override the band knife 34 and are stacked. The roller bearings 46 and 48 are mounted upon threaded studs 58 (Fig. 3) secured by nuts 66 to a bracket 62, the bearing 44 being mounted upon an eccentric portion 64 of a stud 66. In order to between the bearings 44, 46 and 48 and the pulley 42, the eccentric portion 64 may be swung toward an adjacent portion of the pulley until the bearings are forced against the bottom of the annular groove 50, after which a nut 'I'U'is turned to retain the eccentric in its adjusted position.

The bracket 62 is formed integral with a pair of bowed carrier frames 12 connected by an arcuate portion 14 which engages within arcuate guideways 16 of a base 18 secured by bolts 80 to a pedestal 82. The curvature of the guideway 16 is substantially coincident with the uppermost portion of the cutting section 32 of the saw 34, the arrangement being such that when a worm 84 which is in meshing engagement with a gear 86 formed at the under side of the arcuate plate 14 isturned, the pulley 42 is swung about the uppermost portion of the cutting section 32 thereby properly adjusting the pulley 42 in order to insure that the cutting edge of the saw shall remain in a plane as it travels over the pulley. The arcuate plate 14 is held in the guideways 16 by rolls 88 (Fig. 3) which are eccentrically mounted upon the base 18. The carrier frame 72 is normally secured to the base 18 of the machine by screws 90 which are in threaded engagement with the carrier frame and pass through elongated slots 92 formed in the base I8.

The carrier frame 12 comprises a pair of bosses 94 which support a bearing shaft 93 upon which a pair of side plates 98 are swivelcd, the lower ends of the side plates being in engagement with a pair of cams I06 (Figs. 1 and 3) formed integral with a bar I62 pivotally mounted upon the carrier frame 12. The side plates 93 are provided with laterally projecting bosses I04, respectively, bored to receive a shaft I66 to which the matrix drum 28 is keyed. The matrix drum 28 may be conveniently adjusted with relation to the cutting section 32 of the saw 34 for locating the split in the sole blank 24, by swinging a handle I08 of the eccentric bar I02 thereby raising or lowering the side plates 98 and therefore the drum 28 with relation to the cutting section 32. The side plates 98 are conveniently locked to the carrier frame I2 by screws IIO (Fig. 3) which are in threaded relation with the carrier frame and extended through arcuate openings II2of the respective side plates 98.

The presser member 30 which progressively forces the sole blank 24 fed past the saw 34 against the periphery 26 of the rotary drum 28 comprises a plurality of resilient fingers I I4 (Figs. 1 and 2) and a shank portion H6 (Figs. 2 and 3) which is secured by screws I I8 to a sleeve I28 mounted upon a rod I22 supported by the side plates 98.

The feed member 36 is pinned to a shaft I24 rotatably mounted in bosses I26, respectively, of a pair of connected arms I28 (Figs. 2 and 3) the rear ends of which are pivotally supported upon the shaft 96. The left arm I28, as viewed from the front of the machine, has a depending portion I 30, the lower end of which carries a cam roll I 32 arranged to engage a cam I34 (Fig. 3) secured to the matrix drum 28 by screws I36.

The sleeve I20 (Figs. 2 and 3) to which the presser member 30 is secured comprises a pair of levers I38, I39, respectively, (Fig. 2), the lever I38 carrying a roll I40 which is forced by springs I42 into engagement with a ledge I44 formed upon the depending extension I30 of the.

arm I28. The upper ends of the springs I42 are connected to corresponding levers I38 and the lower ends of the springs are adjustably con nected to screws I45 which pass through recesses formed in corresponding side plates 98 and are in threaded relation with nuts I46. The springs I42 cause the cam roll I 32 to be forced against the cam I34 as well as cause the presser member 30 to force the sole against the periphery 26 of the drum 28. In order to insure that the cam roll I 32 shall effectively follow the cam I34 the arms I28 are forced downwardly under the action of a strong spring I48, the upper end of which is in engagement with a yoke I50 formed integral with the side plates 98 and the lower end of which is in engagement with a cross bar I52 whichis secured to the arms I28. As illustrated in Fig. 3 a sole blank 24 has just been positioned in the machine, the cam I 32 being in engagement with the high portion I54 of the cam I34 and being about ready to be moved into engagementiwith a low portion I56 of the cam thereby causing the feed member 36 and the presser member 30 to be lowered to their operating positions.

.WhiIe the cam roll I32 is riding on the high portion I54 of the cam I34 the sole blank 24 is fed into the machine until the toe end of the sole .blank engages a bifurcated gage I58 (Figs.

2 and 3) which when in its lowered operative positionis located immediately ahead of the cutting section32 of the saw 34. gage I58 is pivotally mounted The bifurcated upon a rod I60 and is provided with a groove I82 (Fig. 2) in which engages a screw I64 carried by a sleeve I66 secured to the arms I28. When the arms I28 are raised to render the feed member 38 and the presser member 30 inoperative, the bifurcated gage I58 is lowered to the position illustrated inFig. 3, and when the above members are lowered into operative position, the gage I58 swings section 32 ofthe saw 34, as

ber 30 shall penetrate of the sole blank to a raised inoperative position.

The transverseradius of curvature of the periphery 26, of the matrix drum 28 is substantiallythe same as the radius of curvature of the cutting section 32 of the saw 34. In

I10 have a peripheral speed substantially equal to. that of the periphery 26 of the matrix drum 28. Throughout an arc of approximately 300 the teeth I10 are arranged in two peripheral series I12 (Figs. land 8) located inclose proximity to each other and through mately 60" the teeth are arranged in twoperipheral series I14 which are spaced a considerable distance apart. ,The series 112 of teeth effectively feed the major portion of the sole past the saw and'engage the same along lines I16 indicated in Fig. 9. In order to insure that the presser memthe portion of the sole overlying the cavity I08 instead of. merely forcing the sole into the central part of the cavity, the series I14 of teethare suitably spaced so as to engage the sole along lines I18 of Fig. 9.

In order to limit the penetration ofthe teeth I10 into the sole blank 24 and to insure that when the machine isrunning without any sole blanks being inserted therein, the teeth shall not engage the matrix drum 28 or the saw 34, each of thetarms I28carries an adjustable screw I arranged to engage an abutment I82 (Fig. 3) of a corresponding side plate 98.

. To rotate the matrix drum 28 and the feed member 36 at substantially the same speed and to retain the drum and the feed member in timed itk a gear I84 (Fig-1) which is in meshing enrelation the shaft I08 has mounted upon gagement with a gear I86 mounted upon a stub shaft I88 rotatably supported by a bracket I90 extending from the carrier frame 12. The stub shaft I88 carries at its inner end a crank arm which is operatively connected through a link I94 to a crank arm I93 pinned to the shaft I24 upon which the feed member38 is mounted.

an arc of approxi- When the arms I28 are in their lowered position the axis of the shaft I24 substantially coincides with the axis of the stub shaft I88. The shaft I06 is driven by a pulley I91 which is operated by a belt I99.

In order that the operator may present the solewith its central median plane arranged at a predetermined angle with relation to the plane of movement of the matrix drum 28, the machine is provided with gages I98, 280 (Fig. 2) Which engage opposite sides of the forepart and the heel portions, respectively, of the sole. As. above stated, the sole is positioned lengthwise of the machine by forcing the toe end of the sole blank against the bifurcated gage I58 which is in lowered position when the feed member36 and the presser member 30 are raised in order to permit the, sole blank 24 to be inserted in the machine. Certain features disclosed but not claimed herein are claimed in United States Letters Patent No. 2,107,281, granted February .8, 1938, on an application filed in my name.
